  Note
t  Use brake pedal loader, e. g. -V.A.G 1869/2-, before removing a brake cylinder, a brake carrier or before separating a brake line from the brake cylinder.
t  Use a bleeding bottle, that only comes into contact with the brake fluid, to drain brake fluid from the brake fluid reservoir. Brake fluid is toxic and must never be sucked up by mouth!
t  Already used brake fluid must never be used again.
t  Generally tighten the brake line pipe screws to a tightening torque of 14 Nm.
t  After working on the rear wheel brake: release handbrake; forcefully apply the brake pedal repeatedly to ensure the brake pads go into their normal operating position.
